Recommended Separation Distances Between Portable and Mobile RF Communications
The SERFAS Energy Systemsystem is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the SERFAS Energy Systemsystem can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the SERFAS Energy Systemsystem as recommended below, according to the maximum output

For transmitters rated at a maximum output power not listed above, the recommended separation distance (d) in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
